4 Claims. (01. 248-125) This invention relates to an. orthographicprojection stand and it is one object to provide a stand adapted to holdan object while a draftsman or artist is making a sketch or drawingthereof, the device being of such construction that a platformconstituting an element thereof may be shifted vertically to adjustedpositions and a carrier upon which the object is directly mounted turnedto angularly adjusted positions. It will thus be seen that the artist ordraftsman may view the object from the front, from a position above thesame, or from oneside or the other, according to the views desired whenmaking a sketch or drawing of the object.

Another object of the invention is to so form a bracket carrying theshelf or table that it may be easily shifted vertically along a standardand be frictionally held in adjusted position.

Another object of the invention is to provide a shelf or table which ismounted upon a portion of the bracket for turning adjustment on ahorizontal plane, the object to be drawn being carried by a prongextending upwardly from a member mounted for universal turning andtilting adjustment so that the artist or draftsman may, accuratelyadjust the same after the bracket has been shifted upwardly and theplatform turned to approximately the desired position.

Another object of the invention is to so mount the universallyadjustable carrier that access may be readily had to a set screw and thescrew tightened to create binding engagement with the carrier andfrictionally hold the carrier in an angularly adjusted position.

Another object of the inventionis to provide a. device of this characterwhich is simple in construction, easy to operate, and capable of beingmanufactured atsmall cost.

Fig. 11 is a view looking at the under face of the table or platform.

This improved orthographic projection stand has a post or, standard Iformed from a metal rod of suitable length and rectangular in crosssection. This rod has its lower end portion formed with a dependingthreaded stem 2 which passes through an opening at the top of a base 3and is secured by a nut 4 screwed on its lower end,

as shown in Fig. 1. The base is hollow and of such size that thestandard will be supported upright and prevented from tilting over.

A- bracket 5 is carried by the standard for vertical adjustment thereonand has a sleeve or applying a finger to the seat 18 and applying pocket6 which is closed at it upper end by a,

head or wall I and open at its lower end for insertion of packing 8 andadisc 9. Ears 10 are formed at opposite sides of the disc and formed'with threaded openings II to receive screws l2 by means of which thediscis shifted upwardly to compress the packing in the pocket or sleevefor frictional binding engagement with the standard. An opening l3isformed centrally of the disc to accommodate the standard and at itsopposite sides the annular wall of the pocket is formed with verticallyextending recesses I 4 to receive the ears l0 and guide verticalmovement of' the disc.

Since the screws pass downwardly through the pocket and their heads bearagainst the top wall 1 thereof, the screws may be very easily turnedwith a screw driver to adjust the disc and apply additional compressionto the packing when necessary,

An arm I5, braced by a depending web 16, ex-

pressure, the bracket may be easily shifted downwardly along thestandard to adjusted positions. Since the finger-receiving seat 18 isoffsetwith ..,respect to the sleeve, the bracket may be readily shifteddownwardly and when pressure upon the seat is removed, binding grip ofthe packing will hold the bracket against accidental longitudinalmovement upon the standard. The Weight of the arm and the table l9carried thereby causes canting movement to be imparted to the sleeve andassists in creating binding engagement with the standard and whendownward pressure is. applied to the outer end of the finger ll it tendsto straighten the sleeve about the standard and 'allow it to be sliddownwardly very easily.

The table or platform 19 is formed of Wood or other suitable materialand is preferably oblong as shown in Figs. 2 and 3. The'platform carriesa metal disc 20 which is secured to its under face head of the bolt orscrew is; received in a recess i'l formed in the under face of the tableto accommodate the same. In order to limit turning of the disc 28 andthe table or platform relative to the disc 23, there hasbeen provided apin 28 carried by the disc 23 and projecting upwardly into a slot 29formed in the disc 20. This slot is arcuate and concentric to theopening 25 and only allows limited turning of the disc.

When the device is in use, an object to be drawn is affixed to a prongor carrier 30, as indicated by dotted lines inFigs. 1 and 2. The prongprojects 7 from a spherical block 3i through an opening 32 at the top ofa casing 33 which is of frusto-conical shape and secured upon theplatform by screws 34.- The casing 33 is located centrally of theplatform, as shown in Fig. 2, but the disc 20 is off center, as shown inFig. 3, in order that the block 3| and the seat '35 upon which itrests'will be disposed out of alinement with'the screw 24. Aset screw 36is threaded upwardly through an opening in the' platform and thisopening 31 has an enlarged lower portion which is alined with an opening38 which moves into and out of registry with a companion opening 39formed in the disc 23 so that by passing ascrew' driver upwardly throughthe openings 38 and 39, the screw may be adjusted to lift the seat35into position for binding engagement with the spherical block 3|. Itwill thus be seen that the prong 30 may be allowed turning and universaltilting movement to adjusted positions. Therefore, when the device is inuse, the object may be disposed face toward a person and the bracketshifted upwardly "to a level with his eyes while a front View is beingdrawn and then the platform turned to present a side toward the front sothat a side View may be drawn. After the side view has been drawn at aside of th front View, the bracket is side'view, and front view alsoused individually if so desired.

Having thus described the invention, What is claimed is:
